Answer:The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Given parallelogram SNOW, diagonals SO and NW intersect at D.
If SD = 9x+5 and OD = 13X - 3, find the length of SO
Answers
Answer:
The length of SO is 46 units
Step-by-step explanation:
In a parallelogram, diagonals bisect each other, which means meet each other in their mid-point
∵ SNOW is a parallelogram
∵ SO and NW are diagonals
∵ SO ∩ NW at point D
→ That means D is the mid-point of SO and NW
∴ D is the mid-point of SO and NW
∵ D is the mid-point of SO
→ That means D divide SO into two equal parts SD and DO
∴ SD = DO
∵ SD = 9x + 5
∵ DO = 13x - 3
→ Equate them
∴ 13x - 3 = 9x + 5
→ Subtract 9x from both sides
∵ 13x - 9x - 3 = 9x - 9x + 5
∴ 4x - 3 = 5
→ Add 3 to both sides
∵ 4x - 3 + 3 = 5 + 3
∴ 4x = 8
→ Divide both sides by 4
∴ x = 2
→ To find the length of SO substitute the value os x in SD and DO
∵ SO = SD + DO
∵ SD = 9(2) + 5 = 18 + 5 = 23
∵ DO = 13(2) - 3 = 26 - 3 = 23
∴ SO = 23 + 23 = 46
∴ The length of SO is 46 units

Answers
Answer:
b. 156
Step-by-step explanation:
A "perfect square" is the product of an integer that is being multiplied by itself.
Choice a, 625, is a perfect square because it is the product of 25 multiplied by itself.
25 x 25 = 625Choice b, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, this is the correct answer.
Choice c, 196, is a perfect square because it is the product of 14 multiplied by itself.

Answer:
62
Step-by-step explanation:
50% is technically 1/2 right?
So, if 31 is half of this mysterious number then we just need to times 31 by 2.
Therefore, 31 * 2 = 62.
We can check this by multiplying 62 by .50 (remember that when using percents in an operation we move the decimal over twice)
62 * .50 = 31

The random variable X has mean 12 and standard deviation 3. The random variable W is defined as W=7+2X . What are the mean and standard deviation of W ?
Answers
Answer:
The mean and standard devaition of W are 6 and 31 respectively.
Step-by-step explanation:
Given that:
W = 7 + 2X
Variance (W) = Variance(7 + 2X)
For a term constant term, the variance is zero.
So;
[tex]W = Var (2X)[/tex]
W = 4 × Var(X)
W = 4 × (SD (X))²
W = 4 × (3)²
W = 4 × 9
W = 36
Thus, Variance (W) = 36
The standard deviation of W = [tex]\sqrt{variance}[/tex]
W = [tex]\sqrt{36}[/tex]
W = 6
Also;
E(W) = E(7 +2 X)
E(W) = 7 + 2 × E(X)
where;
mean X = 12
E(W) = 7 + 2(12)
E(W) = 31
Thus, the mean and standard devaition of W are 6 and 31 respectively.
The mean and the standard deviation of W are 31 and 6 respectively.
The given parameters are:
[tex]\mathbf{\bar x_x = 12}[/tex]
[tex]\mathbf{\sigma_x = 3}[/tex]
The definition of W is given as:
[tex]\mathbf{W = 7 + 2X}[/tex]
This means that:
[tex]\mathbf{Var(W) = Var(7) + Var(2X)}[/tex]
So, we have:
[tex]\mathbf{Var(W) = 0 + Var(2X)}[/tex] --- the variance of a constant term is 0
[tex]\mathbf{Var(W) = Var(2X)}[/tex]
This gives
[tex]\mathbf{Var(W) = 2^2 \times Var(X)}[/tex]
We have:
[tex]\mathbf{Var(X) = \sigma^2_x}[/tex]
So, the equation becomes
[tex]\mathbf{Var(W) = 2^2 \times \sigma^2_x}[/tex]
[tex]\mathbf{Var(W) = 2^2 \times 3^2}[/tex]
[tex]\mathbf{Var(W) = 36}[/tex]
The standard deviation is then calculated as:
[tex]\mathbf{\sigma_W = \sqrt{Var(W)}}[/tex]
[tex]\mathbf{\sigma_W = \sqrt{36}}[/tex]
[tex]\mathbf{\sigma_W = 6}[/tex]
The mean is then calculated as:
[tex]\mathbf{E(W) = E(7 + 2X)}[/tex]
This gives
[tex]\mathbf{E(W) = 7 + 2E(X)}[/tex]
So, we have:
[tex]\mathbf{E(W) = 7 + 2 \times 12}[/tex]
[tex]\mathbf{E(W) = 31}[/tex]
Hence, the mean and the standard deviation of W are 31 and 6 respectively.

When a rubber ball is dropped on a particular surface , It bounces back to 8/10 of drop height. The ball's height after bounce x is * (8/10) ^ x times its drop height . What fraction of its drop height will the ball bounce up to after its fourth bounce ? Show your work
Answers
Answer:
The fraction of its drop height after the fourth bounce is
[tex]\displaystyle \frac{16}{625}[/tex]
Step-by-step explanation:
Let's suppose the rubber ball is dropped from a height H0. Every time the ball bounces back it reaches 8/10 of the initial drop height.
The ball's height H(x) after bounce number x is:
[tex]\displaystyle H(x)=H_o\left(\frac{8}{20}\right)^x[/tex]
Simplifying:
[tex]\displaystyle H(x)=H_o\left(\frac{2}{5}\right)^x[/tex]
After the fourth bounce, the height is:
[tex]\displaystyle H(4)=H_o\left(\frac{2}{5}\right)^4[/tex]
[tex]\displaystyle H(4)=H_o\frac{2^4}{5^4}[/tex]
[tex]\displaystyle H(4)=H_o\frac{16}{625}[/tex]
The fraction of its drop height after the fourth bounce is
[tex]\mathbf{\displaystyle \frac{16}{625}}[/tex]
A pair of angles is supplementary if the sum of their measures is 180 degrees. A pair of angels is complementary if the sum of their measures 90 degrees. the supplement of a given angel is 10 degrees more than twice its complement. Let 90-x equal the degree measure of its complement and 180-x equal the degree measure of its supplement. Write and solve an equation to find the measure of the given angel.
Answers
Answer:
The measure of the complement =
= 80°
The measure of the supplement=
= 170°
Step-by-step explanation:
Let
90-x equal the degree measure of its complement
180-x equal the degree measure of its supplement.
We are told in the question that: the supplement of a given angle is 10 degrees more than twice its complement.
Hence, the Equation is;
(180 - x) = 10° + 2(90 - x)
180 - x = 10 + 180 - 2x
Collect like terms
-x + 2x = 10 + 180 - 180
x = 10°
Hence,
The measure of the complement =
90 - x
= 90 - 10
= 80°
The measure of the supplement=
180 - x
= 180 - 10
= 170°

During a sale, a store offered a 40% discount on a particular camera that was originally priced at $450. After the sale, the discounted price of the camera was increased by 40%. What was the price of the camera after this increase?
Answers
Answer:
378
Step-by-step explanation:
Remark
This is a question that all investors in stocks should be aware off. It does not come back to 450 dollars.
Step One
Find out the price of the discounted camera.
40% reduction price = 450 - (40/100)*450
40% reduction price = 450 - 180 = 270
Step Two
Now add 40% onto the new price.
New price = Reduced price + 40% of reduced price
New Price = 270 + 40%* 270
New Price = 270 + 108
New Price = 378
Remark
The reason stock investors should be aware of this is that if you take a 40% loss on a stock it takes more than a 40% gain to make the price of your stock loss back.

This question is incomplete, as the playground diagram and dimensions are missing. However, I'll answer on a general terms.
What this question requires is to calculate the perimeter of the playground.
Assume that the playground is rectangular and the dimensions are: 2 meters by 3 meters.
The distance walked will be calculated using the following perimeter formula.
[tex]Distance = 2(2m + 3m)[/tex]
[tex]Distance = 2(5m)[/tex]
[tex]Distance = 10m[/tex]
If it is a square with 5m as the length of one of its side, the distance would be:
[tex]Distance = 4 * 5m[/tex]
[tex]Distance = 20m[/tex]
So basically, all you need to do is calculate the perimeter of the playground.
